Log of changes to SQUAREM
o first release: August 8, 2010
o second release: August 9, 2010
- fixed a bug in `cyclem1' and `cyclem2' that croped up when testing under Windows 64-bit. This was due to QR-decomposition using LAPACK.
o third release: September 26, 2010
- modified the `cat' statement such that it is effective only when trace = TRUE
o fourth release: December 31, 2010
- There was a bug in the check for convergence in all the 4 functions: squarem1, squarem2, cyclem1 and cyclem2. It was pointed out by Roger Koenker. It is now fixed.
- A slight change was made to documentation regarding the objective function.
o Fifth release: August 10, 2016
- created vignettes with several examples showing how to accelerate convergence using SQUAREM
- created demo examples showing how to use SQUAREM to accelerate convergence
